A new feature in Framer 3, the state machine is incredibly powerful and useful. It allows you to add multiple states to a layer. Think of a state as a set of one or more properties for the layer. A layer can have multiple states, you can add and remove them, and switch or animate between states. All of the states for a layer can have the same animation properties as well, such as the animation curve. You can access any state for a layer at any time. Layers also have a ‘default’ state as well, which are the properties of the layer at time of creation.
